How do I get a javascript variable and pass it into a php variable???

@aaronbdavisApr 17.2006 — #user javascript to set the value of a hidden input element. Then collect it with PHP using the $_GET or $_POST array (depending on which you are using for the form)

@tenniskid493authorApr 17.2006 — #just to make sure I understand...so like put the value into a text area and then turn the style.display of the text area to 'none' and then retrieve it using php???

@aaronbdavisApr 17.2006 — #You don't need to use a textara. Use a hidden input element instead. i.e.

[code=html]<form id="myForm" method="post">
 
 ...
 
 <input type="hidden" id="myHiddenField" name="myHiddenField" />
 
 ...
 
 </form>[/code]

then set the value with JS

[CODE]var e = document.getElementById('myHiddenField');
 e.value = "what ever I like"; //change as needed[/CODE]

Then, when you submit the form, you can collect the value thusly:[code=php]$myVar = $_POST['myHiddenField'];[/code]

@tenniskid493authorApr 17.2006 — #ok..thank you

@bokehApr 17.2006 — #Or like this:

[code=php]onEvent =
 "url='http://location.com/dir/file.php';
 myVariable='value';
 window.location=url+'?phpname='+myVariable"[/code]

@tenniskid493authorApr 17.2006 — #ok..this sort of goes along w/ this. I'm a complete n00b at php so I can barely figure anything out. If I need to make a registration page where someone needs to enter their desired username, desired password, and email address, how would I make this page using HTML and then have a submit button taht then passes all these values into PHP to eventually be stored in a mysql database. Any help, links to tutorials, or advice would be greatly appreciated. Sorry for not offering a start at a code, but I'm completly confused one even how to start this.
